Used PFEIFFER / BALZERS TPH 521PC #186935 for sale

PFEIFFER / BALZERS TPH 521PC is a sophisticated, high-flow and high-performance oil-less rotary vane vacuum pump, engineered for applications that require low pressure control. It offers best-in-class linearity and stability from 0.1 to 1.1 mbar ultimate vacuum, as well as extremely low maintenance needs. BALZERS TPH 521PC is developed with a range of features that make it an ideal choice for demanding applications that require reliable performance, such as load locks and gate valves. The pump is driven by a single-phase asynchronous, self-ventilated motor, and the maximum power consumption is only 600 Watts. The gas ballast valve and outlet air control valve are integrated into the housing, making the unit compact and integrated. The build-in oil management system prevents the oil vaporizing and ensures an oil vapor content in the exhaust flow that is below 0.003 ppm at the maximum rated pumping speed of 5.1 m³/h. The rotor is mounted onto two axial and two radial bearings, and a robust, hardened steel motor shaft drives the rotor. The internal components are designed for maximum service lifetime and quiet operation. An isolation buffer and a gas ballast valve located at the exhaust port reduce vibration and minimize noise levels, making the TPH 521 ideal for use in quiet or noise-sensitive environments. The TPH 521 features advanced motor protection, adjustable motor protection, and integrated service indicators for protection against faults and failure. The diagnostic software of the pump allows for fast and easy fault recognition and problem solving. The single-phase drive is independent of a mains grounding, making it suitable for use in sensitive environments and applications. PFEIFFER TPH 521PC is a low-maintenance pump requiring only occasional maintenance. The momentary self-purge function of the pump enables the user to maintain their own vacuum system to the highest standards. In addition, the in-built lubricant reservoir makes maintenance-free pumping possible. Overall, TPH 521PC is an advanced and reliable oil-less vacuum pump that is suitable for a variety of demanding applications. With its excellent noise suppression, protection features, and low-maintenance requirements, it is an ideal choice for any process requiring reliable, accurate vacuum control.
